   One file, no framework, no external fonts, no CDN. The whole site is a few
   static files on Cloudflare Pages, which is what keeps it free; a font or a
   framework fetched from someone else's CDN is the one thing that could stop
   it working on a day we are not looking.

   The palette is the server's own: deep charcoal, parchment, and the coin gold.
